Question 1

In titrating 0.20 M hydrochloric acid, HCl, with 0.20 M NaOH at 25°C, the solution at the equivalence point is

◦ 0.20 M NaCl
◦ very acidic
◦ slightly acidic
◦ 0.10 M HCl and 0.20 M NaOH
◦ 0.10 M NaCl

Question 2

In titrating 100 mL of 0.10 M HCl (aq) with 0.10 M NaOH, the pH does not change a great deal initially. Why is this?

◦ The amount of OH–has no effect on the pH of aqueous solutions.
◦ The H+ from the HCl (aq) acts like a buffer.
◦ The major species when the acid and base are mixed form a buffered solution.
◦ The statement “In titrating 100 mL of 0.10 M HCl (aq) with 0.10 M NaOH, the pH does not change a great deal initially.” is not true.
◦ None of these are correct.

People who have myopia, or nearsightedness, are not able to see objects at a distance but only up close. It occurs when the cornea is either curved too steeply, the eye is too long, or both. This condition is progressive and worsens with time. More than 100 million people in the United States are nearsighted, but only 20% of those are born with the condition. Diet, eye exercise, drug therapy, and corrective lenses can all help manage nearsightedness.
